N2 - Dye-sensitized solar cell (DSC) is highly focused because of low-cost. Generally, DSC was composed of photoelectrode, dye, electrolyte, and counter electrode (CE). Sputter-coated Pt on the fluorine doped tin oxide (FTO) electrode was mainly used as CE, however it was expensive and low speed fabrication. In this study, we tried to apply the spray mode of the electrostatic inkjet printing for fabrication of CE. Fundamental characteristics were investigated with the spray-coated Pt CE, the sputter-coated Pt CE, and FTO CE. Conversion efficiency was very low in case of FTO CE. Efficiency of spray-coated Pt CE was 3.6%. The efficiency was a little lower than that of commonly used sputter-coated Pt CE because Pt was not completely coated on the FTO glass by the inkjet printing. These results indicated that spray-coated Pt on FTO glass had possibility to be used as CE of DSC.
